WunderlistProOffersNewCollaborationToolsToBusinessUsers

Wunderlist Pro is here. The first premium model of the cross platform productivity app is available now for the iPhone/iPod touch, and Mac.
First announced earlier this month, Wunderlist Pro brings collaboration tools to the to-do list service for the first time.
Features include:

Assigning - now you can add an extra level of accountability and assign tasks to your colleagues and friends.

Unlimited subtasks - sometimes the task on hand is so big that you need to break it down into small manageable subtasks. Now you can add as little or as many needed to get the job done.

Backgrounds - Wunderlist Pro subscribers will have access to eight new backgrounds - from a minimal dark wood and soothing sands to vibrant florals and the Paris cityscape, plus a whole lot more!

Says Christian Reber, 6Wunderkinder founder and CEO:

Over the past two years we have seen Wunderlist go from being solely a personal productivity app to it becoming part of our users’ daily working lives. Now, today, we start the next chapter of our journey with the arrival of Wunderlist Pro.

Wunderlist first launched in 2010. In 2012, the service was radically redesigned.
To update to Wunderlist Pro, you must make an in-app purchase. The price is $4.99 per month, or $49.99 per year. The upgrade carries through to all applications, regardless of platform. At launch, the Pro service is only available on iOS and OS X. Android and Windows versions will follow.
The universal Wunderlist app is available for download in the App Store. The Wunderlist for Mac application is available in the Mac App Store. Both applications, like the regular Wunderlist service, are free.
